An O ( n log n ) algorithm for finding edge span of cacti
PublikacjaLet G=(V,E) be a nonempty graph and xi be a function. In the paper we study the computational complexity of the problem of finding vertex colorings c of G such that: (1) |c(u)-c(v)|>=xi(uv) for each edge uv of E; (2) the edge span of c, i.e. max{|c(u)-c(v)|: uv belongs to E}, is minimal. We show that the problem is NP-hard for subcubic outerplanar graphs of a very simple structure (similar to cycles) and polynomially solvable for...

Badania betonów o przyspieszonym twardnieniu
PublikacjaBadania wykazały, że możliwe jest uzyskanie tak wysokich wytrzymałości wczesnych betonów, że całkowicie zbędna staje się ich obróbka termiczna. Stosując odpowiedni cement klasy 42,5R i prawidłowo dobrana mieszankę upłynniającą można uzyskać już po 12 godz. wytrzymałość betonu około 35MPaa przy klasie cementu 52,5R nawet około 50MPa i to przy ilości cementu nie przekraczającej 400 kg/m3 betonu.

Badania betonów o przyspieszonym twardnieniu.
PublikacjaCharakterystyczną cechą betonów stosowanych w prefabrykatach jest ich wymagane szybkie twardnienie, umożliwiające skrócenie cyklu produkcyjnego i możliwie najszybszy transport elementów do odbiorcy. Do niedawna większość zakładów prefabrykacji stosowała w omawianym przypadku obróbkę hydrotermiczną betonu. Wprowadzenie do praktyki różnego rodzaju domieszek i dodatków umożliwiło wyeliminowanie z zakładów procesów termicznych.

Contact with coupled adhesion and friction: Computational framework, applications, and new insights
PublikacjaContact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously, but included in the theoretical models by Mergel et al., (2019). We here develop a corresponding finite element framework that captures 3D finite-strain contact of two deformable bodies. This framework is suitable to investigate sliding friction even...
